Crane provided with lifting trolley and suspension trolley and capable of rotating at any angle

Abstract

The application discloses a crane with a hoisting trolley and a suspension trolley that can rotate at any angle, including a double-girder bridge frame with end girders and main girders; both ends of the end girders are provided with cart driving devices; rails are provided under the main girders; The two ends of the track are connected to the stop device; the two rails are connected with a lifting trolley and a suspension trolley; the lifting trolley is provided with a hook-type lifting device; the suspension trolley is provided with a rotation mechanism; the boom shaft in the rotation mechanism The lower end is connected to the cantilever member, and the upper end is connected to the collector slip ring; the electric hoist is installed on the cantilever member and can move back and forth along the cantilever beam; the cantilever beam is under the main beam and can rotate at any angle; Set up a safety hook; there are a number of pick-up racks on the top of the double-girder bridge, and two rows of guide rails are connected under the pick-up racks; movable hanging cables are connected to the guide guide rails.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a hoisting trolley and a suspension trolley that can rotate at any angle. Background technique [0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pull...

AI Technical Summary

Problems solved by technology

[0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled obliquely, and the items farther away from this plane (such as outside the workshop door, outside the span) cannot be hoisted. At this time, it can only be transferred with the help of other transportation equipment. Usually, the car drives into the workshop to lift the goods under the hook. Go to the hook to hand over the goods, and some set up a special cantilever crane at the workshop door (or workshop aisle) to transfer and dispatch the goods outside the workshop, first hoist the goods into the place where the crane hook of the workshop can reach , and then the cargo is hoisted by the crane to other stations in the workshop. The existing bridge crane used in this working condition cannot directly transfer the cargo with the workshop next door, and must use other transportation equipment to schedule operations, which brings considerable inconvenience. It also wastes manpower and material resources
